TAS5634是一款PWM输入D类放大器功率级,可在58V标称电源电压下提供2 x 300W(6Ω)或1 x 600W( 3 *)的输出功率.58V电源电压支持较高阻抗的扬声器负载,其中BTL为6Ω,PBTL为3Ω。集成式MOSFET和全新栅极驱动方案具有较高的峰值效率和较低的空闲损耗,能够减小散热器解决方案尺寸。
TAS5634使用闭环反馈设计,具有恒定的电压增益。开关模式电源(SMPS)的使用,使得内部匹配的增益电阻器可确保实现较高的电源抑制比较(PSRR)和较低的输出噪声。
TAS5634是一款兼容TI的数字输入(I2S)音频处理器和调制器产品组合的全集成式功率级,与TAS5548和TAS5558类似,也是一个完整的数字输入D类放大器.TAS5634采用表面安装44引脚HTSSOP封装,是PWM输入D类功率级兼容引脚产品系列(包括TAS5612LA,TAS5614LA和TAS5624A)中的一员
